To all whom it may concern:

inafter more fully. set forth and Be it known that I, JAMES D. LAMONT, a.citizen of the United States,` residing at' .Detroit, in the county ofWayne, State.

o'f Michigan, have invented certain new and useful Iinprovenfients inElectric Cookers;

and I do declare the following to be a full,

clear, and exact description of the'invention, such as will enableothers' skilled in the artto which it appertains to make. and

use the same, reference being had to the accompanying drawings, and tothe characters of reference ymarked thereon which form a part ofthisspeciiication.

This invention relates to an construction and arrangement of parts'hereout particularly in the claims.

The objects ofthe invention are to prol vide a simple and eilicientelectric heater or stove and to place said stove in a case or cookingreceptacle rendered non-conductive of hea-t wherein the heat generatedhy the.

stove maybe' confined within a small area,

provisionbeing made forreadily'detaching .the heater or`stove from thereceptacle or -i casing; for connecting and disconnecting viate thepossibility of short-circuiting theA through a casing theserVi'Ce orconductorwires thereto; for insulating the electrical 'conductors toobcurrent and to .prevent the contact of moisture with any'of theexposed contacts or electrically conductive parte,

The above objects 'are `attained the structure illustrated intheaccompanying drawings, in vwhich f Figure 1. is a `centralv verticalsection cooking-vesselinl place upon'the heaterwi h.

in the casing or receptacle. Fig. 2 is a hori- Zonta-l section as online2-2 o fEig. 1. Rg.' 3- is an' elevation of the socket plate intowhich. the ends ofthe conductors of the re-- lsistencecoils extend-toform contact pins.

Fig. e is a sectional view as on line 4-4 of Fig.j3. 5 is a fragmentaryview insee- .tion through thegsocket pla-te andneck of theheater, saidparts being separated.

The caseor receptacle in which the-heater electric stove. and therinoticcooker, and consists in the' pointed and heater', or'stove made' inaccordance with my invention, showing a yother and the space` betweenthem filled with mineral wool 3 orother like/material which isnon-conductive lof .heat.

'ro Entsworn VVithin'the central' portionof the-oasev is a cylindricalchamber' Il closed at the. top-by to make a tight closure, the top ofthecase y a removable cover 5 whichisiitted into the. outer opening of.said chamber in a manner l proper' being closed by a supplementary.

cover 6.

The stove or heater wherein the heat for cookingfis generated, consistsof a hollow circular body portion 7 closed by a remov ablehottorn 8having feet 9 which elevate the bot-tom of thelheater from thebottom of'the chamber 4. The heater or stove is .preff 'erably cast fromsuitable'inetal and formed 'integral therewith and projecting later allytherefrom is -a thollow, tapered neck portion 10. Within thehollow.hea-ter' isai suitable resist-ance coil 11. 1- From theterl-f minalslof the coil 11 extend; the contact pins- `12 and A13, respectively,whichpa through and are embedded'in va filling-of. plastenof Paris orlike non-conductivefmaterial 14 contained within the hollowneckl0fof...tlie

heater, the ends of said pins .projecting 4tl'iroiigh the'hollow tenons10" extending be` portion, as'

yond the terminal of the neck. clearly shown in Figs and'4. I4`orinedhrough the wall'of the case and communicating` with the central chamberti material of poor conductivity.v The inner portion of the bushii'ig15.is tapered to receivethe neck 10 v'of the heater which coi n` ci destherewith and is adapted tovt therein.'

socket plate 1,6.l The tenons 10"o f the necky of the heater extendthrough the registering apertures 17 in. thebottom of the'socket-platethereof near the bottom, is 'ano ening which is seated a bushing 15 o flea or other 16 and said parts are securely-fastened'together by meansof a screw 19 which passes through the bottom of the socket plate into atapped center piece 20of the neck which crosses between and connects thesides thereof. By this arrangement, theneck'of the heater `andthe socketvpla-te l-may be se'- 'curely fastened together in a manner to enablesaid pa'rtsto be readily disengaged-,L

when desired. :The outer ends ofthe cenv `tact pins'12 and 13'lie'.'within the socket plate infpfisition rto y'receive the plugs 21jvand duetors in a manner to etlect a short cireniting thereof. it willalso he noted that the electrical conductors are so insulated as toprevent :i grounding' of the current on any i'l the metalparts of thecase.4

By employing the individual plugs 21 and 22' to connect the serviceWires 23 and. 2l- Wit-h the terminal pins ot' tl e resistance coil, anylateral straining of said pins is avoided, thereby obviating thepossibility ot' bre/ale ing,` away the insulating material from aroundsaid pins and insuring al ways a readyandA easy connection of theservice -wires with the terminals oit the resistance coil oit theheater. lty 'will also be observed that by removing' the screw 19 whichconnects the socket plate With the neck the heater, said heater may bereadily removed from thc chamber l ofthe case for the purpose ofcleaning it or for making' repairs thereto:4 when necessary. Byinclosing` the heater ivithin a chamber Whose Wall is spaced t'rom theouter wall oit 'the case hy a filling' of nonconductive material7 theheat which is ajenerated by the heater is prevented. from radiating` andis retained Within said chamber, enabling the electric current vwhichgenerates the heat Within the heater to be turned oli after thetemperature of said chamber has been raised to the required degree7 therctained heat completing the operation of cooking the 'food Within thevessel 25 which rests upon the heater Within said chamber? 'Withoutrequiring the consumption ol addi tional current. is the heatcannotescape from the chamber f1tby radiation or conduction, a very hightemperature may be retained in said chamber for many hours "titer theheating current has been turned ont, enabling the operation of cookingto be accomplished in a ver ine; pensive mannen Having thus fully setforth my invention,

'what l clairn as new and desire to secure by tietters Patent? is:-

l. A cooking' apparatus having' a central cooking` chamber provided withan opening' in the Wall thereof, a bushing'o't insulating' materialfitted into said opening a heater Within said chamber detachedtheretroin, a resistance coil within said heater having terminalcontacts, thc terminal contacts of said coil ii'acsiunj through saidbushing; in the Wall oi the chamber and insulated therefrom, and meansfor detachzibly connectingr the service Wires with the projectingterminals oit said coil.
